HTML Checking for Large Sites
Rocket Validator integrates the W3C Validator HTML checker into an automated web crawler.
HTML issues tagged as xmlns:link.
The only permitted value for the xmlns:link attribute is http://www.w3.org/1999/xlink.
Although using https in the URL looks like it’s going to be more secure, in fact this URL is not used to connect it to, only to declare the namespace.
12,500 Accessibility and HTML checks per week. Fully automated.
Let our automated scanner check your large sites using Axe Core and W3C Validator.
